Record Summary As PDF on Email for lookup record

Is it possible to include a Record Summary as a PDF in an email if the Record Summary is from a lookup field?

Perhaps by fetching the record and then qualifying the record summary in the email.

Lookup_Record = Student_Record [ID = Iinput.Lookup_Field];
